I mean, it's not that hard to put 2 and 2 together when you see it happen enough.
We could also get into serial killers who crossdressed, it crops up a fair bit with them.
Especially underwear.
Ed Gien, not
technically a serial killer but let's be real he would have been if not caught.
Jerry Brudos, the "Shoe Fetish Slayer" would frequently dress in the clothes of women he killed and take pics.
Russell Williams, he broke into his victims' homes, raped and murdered them, took their clothes, wore them and took pics.
Herbert Baumeister, closeted gay man who would crossdress on occasion to fulfill his sexual fantasies.
William Heirens, the "Lipstick Killer" would crossdress to, according to him, enter a different state of mind as he was pretty mental.
Douglas Clark, one of the "Sunset Strip Killers" was a complete sexual lunatic who, among many other things, engaged in crossdressing.
Really makes you think, huh?
